High-bay luminaire with heat-dissipating housing defining a cavity with angled inner wall

Abstract

A high-bay luminaire includes an upper housing having an outer wall with an interior surface defining an interior compartment, and outer wall with an angled portion extending at an oblique angle towards a center of the interior compartment; a plurality of first heat fins extending from the exterior surface of the outer wall; a base connected to the upper housing; a light emitter connected to the base; a lens connected to the base and positioned below the light emitter; and a driver connected to the angled portion and operatively connected to the light emitter.

What is claimed:

 a base connected to the upper housing; 
 a light emitter connected to the base; 
 a lens connected to the base and positioned below the light emitter; and 
 a driver connected to the angled portion and operatively connected to the light emitter. 
 
     
     
       2. The high-bay luminaire of  claim 1 , wherein the base includes a plurality of second fins aligned with the first fins. 
     
     
       3. The high-bay luminaire of  claim 1 , wherein the upper housing includes a bottom wall and a flange extending from the bottom wall, and the base includes a hub extending from an inner portion to mate with the flange. 
     
     
       4. The high-bay luminaire of  claim 1 , wherein an airflow channel is defined between the upper housing and the base to reduce heat transfer between the upper housing and the base. 
     
     
       5. The high-bay luminaire of  claim 1 , wherein the driver is connected to the angled portion by a driver bracket. 
     
     
       6. The high-bay luminaire of  claim 5 , wherein the driver bracket has a substantially V-shaped configuration including a first side and a second side connected to a lower wall, and wherein the driver is positioned by the first side. 
     
     
       7. The high-bay luminaire of  claim 6 , wherein a second driver is positioned by the second side. 
     
     
       8. A high-bay luminaire comprising:
 an upper housing having an outer wall including an exterior surface and an interior surface, the interior surface defining an interior compartment, and a plurality of first heat fins extending from the exterior surface, the outer wall also including a first angled portion extending at an oblique angle toward the center of the interior compartment and a second angled portion extending at an oblique angle toward the center of the interior compartment; 
 a base connected to the upper housing; 
 a light emitter connected to the base; 
 a lens connected to the base and positioned below the light emitter; and 
 a driver bracket positioned in the interior compartment and configured to retain a first driver against the first angled portion. 
 
     
     
       9. The high-bay luminaire of  claim 8 , further comprising a sensor removably connected to and extending from the base. 
     
     
       10. The high-bay luminaire of  claim 8 , wherein the driver bracket includes a lower wall, a first side extending from the lower wall at an oblique angle and a second side extending from the lower wall at an oblique angle. 
     
     
       11. The high-bay luminaire of  claim 10 , wherein a first ledge extends from the first angled portion and a second ledge extends from the second angled portion, and wherein a first flange extends from the first side and a second flange extends from the second side, and wherein the first tab engages the first ledge and the second tab engages the second ledge. 
     
     
       12. The high-bay luminaire of  claim 10 , wherein a pair of tabs extend from the first side toward the first angled portion. 
     
     
       13. The high-bay luminaire of  claim 8 , wherein a first driver is retained against the first angled portion by the driver bracket. 
     
     
       14. The high-bay luminaire of  claim 13 , wherein a spacer is connected to the second side of the driver bracket. 
     
     
       15. The high-bay luminaire of  claim 13 , wherein a second driver is retained against the second angled portion by the driver bracket. 
     
     
       16. A high-bay luminaire comprising:
 an upper housing having a bottom wall and an outer wall defining an interior compartment, wherein a plurality of first heat fins extend from an exterior surface of the outer wall; 
 a base connected to the upper housing, the base includes a plurality of second fins aligned with and separated from the first fins to define a first space, and an inner section facing but separated from the bottom wall to define a second space; 
 a light emitter connected to the base; 
 a lens connected to the base and positioned below the light emitter; and 
 a driver positioned in the interior compartment, 
 wherein an airflow channel is defined by the first and second spaces. 
 
     
     
       17. The high-bay luminaire of  claim 16 , wherein a flange extends from the bottom wall and a hub extends from an inner portion to mate with the flange. 
     
     
       18. The high-bay luminaire of  claim 16 , wherein the upper housing includes an angled wall extending from the outer wall at an oblique angle toward the center of the interior compartment, and wherein a driver bracket having substantially V-shaped configuration retains the driver against the angled wall. 
     
     
       19. The high-bay luminaire of  claim 16 , wherein the base includes an outer section and a middle section positioned between the outer section and the inner section, and wherein the outer section, middle section, and inner section are spaced vertically from each other.
